We have the friction welding machine. Equipment: - PLC: 317T-2DP - Control unit: CU320-2DP - Motor: 1FK7 - Absolute encoder Also we have four servo motors which should attract two rings. See picture 1.jpg. Problem in one of those motors. (Ganascia DX01). This motor is master for another three. When we try to move Ganascia DX01 we get an fault: 5011: Range limit of the incremental actual value exceeded (parameter 1:16). See picture 2.jpg There is a solution on siemens support website: https://support.industry.siemens.com/cs/ww/en/view/40786053 According this solution and manual S7-Technology A5E00251798-04 we was trying to execute function: homingMode:=SET_OFFSET_OF_ABSOLUTE_ENCODER_BY_position (MC_Home, Mode = 5) After that we got 8045 fault from MC_Home. According manual S7-Technology it means: illegal command with current status. See picture 3.jpg So, the questions is: what that fault means? Which conditions we need to executing MC_Home function for reseting incremental limit?

Hello, there must be no drive fault and it must be possible to run the motor. For a test, it is possible to use "Virtual Axis". MC_Power; MC_Home See chapter 6.2 https://support.industry.siemens.com/cs/ww/en/view/30119663 3.1.5 Real and virtual axis |

Thanks for your answer. We had solved problem. We found that " incremental actual value" is calculated with very large OFFSET value, which we can't reset because there is axis in fault. The solution is: we deleted entire axis from the copy of actual project version and then we comiled and uploaded entire system. After that, we uploaded actual project version but with problem axis. So fault is gone and the OFFSET value has been reset.
